Abstract
A thin film magnetic head is disclosed that is capable of improving the thermal efficiency of a heater. A thin film magnetic head includes: a lower shield layer; an upper shield layer; a reproducing element that is provided between the lower shield layer and the upper shield layer; a recording element that is formed on the upper shield layer; a heater that generates heat to expand at least one of the reproducing element and the recording element such that the reproducing element and/or the recording element protrude toward a recording medium; and a shunt line that applies a reference potential that is equal to the potentials of the lower shield layer and the upper shield layer to a magnetic layer of the recording element. In the thin film magnetic head, the shunt line is connected to the magnetic layer of the recording element at a position that deviates from the center of a heat generating region of the heater in a track width direction.
